PCT No. PCT/CH81/00098 Sec. 371 Date Apr. 22, 1982 Sec. 102(e) Date Apr. 22, 1982 PCT Filed Aug. 28, 1981 PCT Pub. No. WO82/00751 PCT Pub. Date Mar. 18, 1982.A U-shaped part (1) of which the two parallel branches (1a, 1b) may slide in corresponding grooves (9a, 9b) of a casing, forms a key receiver ring. In a chamber (13) of the casing (2) there is provided a mechanism comprising an oscillating part (3) provided with a spring blade (11) and having a series of notches (14) forming latch locks. The free end of the longer branch (1b) of the U-shaped part (11) is provided with a bolt (4). A maneuver button (10) allows to oscillate the oscillating part (3) against the action of its spring (11) to disengage the bolt (4) of the latch lock (14) where the spring was keeping it engaged, thereby allowing to disengage from the casing (2) the shorter branch (1a) of the U and to bring the bolt (4) selectively facing one of the latch locks (14) so that the length of the portion of the ring (1) being outside the casing corresponds to the number of the keys engaged on that portion. By releasing the button (10), the spring (11) produces the cooperation between the bolt (4) and the latch lock (14) thereby locking the ring (1) on the casing (2).

Description

- 1 - Key ring with security lock of its ring

  the quantity is variable and can be adjusted according to the

  number of keys hanging on it.

  The present invention relates to the realization of a

  keys comprising a device for adjusting the size of its ring, variable according to the number of keys that one wants to hang, and prohibiting the accidental opening of

the ring, after locking.

  In the field of key rings, previous inventions

  essentially consist of spiral rings or half

  rings resting on a support, opening and closing

  thanks to the simple elasticity of the metal used for their

  tion. Some of the more elaborate ring opening and closing systems consist of:

  Either in a bracelet with an inner notch in the-

  which is housed one end of ring wrought ergot, the other end of the ring sliding in the bracelet; Or in articulated devices, actuated by a small lever of lateral force;

  Either in a simple or inverse thread wheel,

  on a ring of ovoid form whose two ends are fileutened. And there is also a wall key ring with a movable flap folds, after installation of the keys, on a wall mounted panel and provided with a spring clip that ensures the

  maintaining or clearing the moving shutter.

  The present invention aims to offer the user

  a keychain allowing easy housing of a growing number -

  or decreasing keys, thanks to a ring whose variable size

  can be set according to different positions and the

  rusting and opening are provided by a mechanism incorporated in the body of the key ring and which allows to give the desired size to the ring, and to prohibit the opening

accidental.

  The first device of the invention consists of a rod

  made of metal or hard plastic, curved in the shape of half

  ring extended by two parallel branches of length

  the largest with a lug at its end or more

  skewers on the part of its length exceeding the length

  of the smaller of the two branches.

  -2 - This rod portion which can also, depending on the case, be threaded or notched, is integral with the mechanism housed in the body of the key ring and ensuring the opening9 the adjustment of the size of the ring and its locking after setting up of the keys.

  According to a first variant, the ring made of metal or

  Hard plastic may have the shape of an arc of about 340 degrees at most, one end of which is anchored to

  an axis fixed inside the body of key-rings and whose other

  end is present, or not, a pin or door, or not, a

series of notches.

  According to a second variant, the ring may have the

  form of a hyperbolic spiral whose starting point is

  created on an axis located inside the housing constituting the

  body of the key ring and whose end carries, or not, a se-

  of notches or, present, or not, a lug.

  The second device of the invention consists of a bot-

  tier closed by a cover or, openable in its thickness and constituted by the assembly of two symmetrical half-parts and having on the inside: Either two parallel grooves of unequal length, in

  which slide the two branches extending the half-year

  first device; Let an axis on which is anchored one of the ends of

  the arc of circle or fixed the starting point of the hyper-spiral

  bolique and around which this arc or spiral can

  turn in one direction or the other.

  This box which can be shaped as desired, circular, square, oblong, spherical or spindle, and which may have a concave curvature in the form of a semicircle whose diameter corresponds to that of the half-ring presented by the stem

  recoated, provides sufficient interior space to accommodate the

  ensuring the operation of the key ring.

  The third device of the invention is intended to

  the opening, adjusting the ring size and locking it. It is a mechanism that can consist of a notched striker in which is fitted the longest end pin of the two parallel branches extending the half-ring formed by the

  curved rod of the first device.

  - 3 - This striker, located between the two inner gorges that

  includes the shoemaker, is mobile around one of its extremes

  your; it is held in the locking position by a resistor

  Extends in extension and has at its other end a button protruding slightly on the bottom of the box. Pressing this button allows to move, by compression or flexion of the spring,

  the striker whose erasure frees the ergot ending the longest

  two branches extending the half-ring formed by the

  Curved geometry of the first device.

  The released lug allows the sliding, in each of their groove, of the two parallel branches of the curved rod, until opening of the ring obtained by the output of the box of the most

short of the two branches.

  The keys once in place, the inverse sliding makes it possible to close the ring by reintroduction in its groove of the shortest of the two branches extending the half-ring of the first

  device. The ring size being chosen according to the name

  A number of hooked keys and their ease of handling, the released striker resumes its initial position thanks to the thrust of the spring in extension and comes to block the lug ending the longer of the two branches of the curved rod, by embedding this lug in one or the other of its notches corresponding to the

chosen ring size.

  In the case where the end of the longest of the two

  The curved rod of the first device is threaded, the unlocking and locking, after choosing the best ring size according to the number of keys hung, are provided by a wheel, eccentric or not, blocking the rod on the position chosen. In the case where the end of the longest

  of the two branches is notched, one can ensure, thanks to a system

  ratchet system, unlocking and locking the ring.

  In the case of the two variants according to which Vanneau en

  metal or hard plastic material has the respective shapes

  of an arc or a hyperbolic spiral turning

  turn of an axis on which are anchored either one of the ends of

  the arc of circle is the starting point of the hyperbolic spiral

  the mechanism controlling the unlocking and locking of the arc or the spiral, after selecting the ring size best suited to the number of hooked keys, may consist of a ratchet or ratchet system, or again, in a system comprising a jaw blocking the bow of

  circle or spiral through the pressure of a spring in ex-

  tension that can be relaxed, to unblock the ring, by sim-

  full pressure on the walls of the box.
